Since alot of people have been asking for this... ok... Before i start please...
Take note: This quest does not apply to main NPC characters. Eg: Lucify. He is a swordsman but you won't get this quest.
1. Hire/Recruit any classes to your guild that you desire to get the "Spirit" items, unlocking the final skill for that class. Eg: Get a Swordman to get Swordman "Spirit"
2. Level him/her till him/her can change to upperclass (Job 30) and get him/her to be "Good Friend" status with you.
3. When you achieve the above, go back to your own guild, visit your kafra and change them to upperclass. Eg: Acolyte to Priest
4. Now visit their respective classes guild and talk to the npcs standing by the side. One of them will give you a quest.
5. Complete the quest and you will get the "Spirit" item, unlocking the final skill/skills of that class. Eg: Knight guild mate quest reward you with "Spirit of Knight". When you change to a knight, you will notice the extra skills at the end of the skill page
Q: I did the quest but i never get the item!!! I think you did the wrong quest... There's another quest for your guildmates when they are 1st class. Eg: Acolyte. This quest only give your guildmate extra job exp and make them "True Friend" status wth you.
Q.Do i need to be the same class as the guildmate's class to get the spirit item?? Nope. You can be any class you want.
Q.Will the extra skills disappear if i change to other classes?? Nope. The spirit items are valuable items that will always be with you after you get them.
